WebNumber are generally stored in binary, so, for instance 135 is represented as 10000111, i.e. 128 + 4 + 2 + 1. Bitread allows you to inspect a specific bit of a number, so bitRead (135, 0) = 1, bitRead (135, 5) = 0. In particular, passing 0, 1, 2 or 7 as argument to bitRead (135, *) would return 1, whereas otherwise it would return 0.
